The SolarMax 20A charge controller is a reliable, user-friendly solution for managing solar energy in off-grid systems. With intelligent charging and essential safety protections, it ensures

The SolarMax 20A PWM Solar Charge Controller is a compact, intelligent regulator designed to manage power from solar panels to batteries safely and efficiently. Supporting both 12V and 24V systems, it delivers up to 20 amps of charging current—perfect for small to medium solar setups such as RVs, cabins, and home backup systems.

Built-in safety features include overcharge, over-discharge, short circuit, and reverse polarity protection. The controller uses Pulse Width Modulation (PWM) technology for improved battery life and stable system performance. A clear LED interface or LCD screen (depending on the model) displays battery status and system operation at a glance.

Key Features:

• 20A maximum charge/discharge current

• Compatible with 12V/24V battery systems (auto-detect)

• PWM charging for better battery health

• LED indicators (or LCD display, depending on model)

• Built-in protections: overcharge, short circuit, reverse polarity, over-discharge

• USB ports (on select models) for direct device charging
